PETROLEUM -BURNER FOR COOKING, 800.

Specification forming part of Letters Patent No. 50,121, dated September26, 1865.

To all whom it may concern:

Be it known that I, JOHN P. HAYES, of the city of Philadelphia, in theState of Pensylvania, have invented a new and useful Improvement in Oilor Petroleum Burners for Heating and Cooking; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and 0perationof the same, reference being had to theaccompanying drawings, making a part of this specification, in whichFigure 1 represents a vertical half-section of the said improved burner;Fig. 2,a plan view of the upper side of its heating-chamber, below thedotted line a: of Fig. 1; and Fig. 3, a like view of the perforateddiaphragm or bottom of the said chamber,below the dotted line Likeletters of reference indicate the same parts when in the differentfigures.

The object of my invention is to produce a burner for cooking andheating by the combustion of oil, petroleum, or other hydrocarbons, thatwill give a much larger and more intenselyheated flame than any burnerheretofore produced for the same purposes. It consists in the combinedarrangement of a bent heating -tube and a heating-chamber, (applied tothe upper part of any suitable supporting stand or base connected withan appropriate reservoir of the oil orpetroleum,) so that a small streamof the hydrocarbon will be forced downward from the tube and impingeagainst the upper side of the top of the heating-chamber in such amanner that, when ignited,the flame will heat both the tube and thechamber with their contents and produce an enlarged andintensely-heatedhorizontal flame for the purposes specified.

In the drawings, A B is the heating-tube; O, the heating-chamber; D E,the supporting stand or base, and F, a short section ofa tube intendedto lead into any suitable supplyingreservoir.

The base or stand I) E is a cylindrical metallic cup, having a flangedbottom sufficiently large to support the whole burner firmly in avertical position. At one side, near its hottom the tube F, which leadsto the reserinserted, and the interior of the cup is filled with smallbroken fragments of pumice-stone or gravel, e. The heating-chamber O isalso made of metal, and consists of a circular top plate, 0, and acircular perforated bottom or diaphragm, 0 each united by their edges toa hollow case or cylindrical band, 0 so as to form together a shallowchamber, 0, between them, at the upper end of the band 0 while the lowerend of the cylinder, formed by the band 0 being adapted for the purpose,is screwed tightly over the upper end of the stand D E. (See Fig. 1.)

The tube A B is bent into one or more coils, a, or into a goose-neck,and has one of its ends inserted tightly in the top plate, 0, at a pointnear the edge of the latter, (see Figs. 1 and 2,) so as to communicatewith the interior of the heating-chamber C, while its other end, a ,isstraight and brought so as to point dowa ward or in a perpendicularposition over the center of the top plate, 0, of the chamber U, and withits said free end a at about half an inch, more or less, above the saidplate. (See Fig. 1.) The free end a of the tube A B is closed with theexception of avery small hole, I), through the center of the plug orclosingdisk.

Operation The burner described being placed in an empty fire-place orgrate, and connected by means of the pipe F with a sufficientlyelevatedreservoir of the combustible fluid to be used, and the stopcock of thesaid reservoir opened, the fluid passes in a diffused manner through thefragments or gravel, e, thence (as indicated by the arrows) through theperforated diaphragm or bottom 0 into the heating-chamber U, thence upthrough the tube A B to the small orifice b, and, passing through thisin a comparatively small stream, it finally impinges directly downwardagainst the center of the top plate, 0, of chamber 0. This stream is nowignited, and the flame soon heats both the tube above and the chamber 0below, and the combustible fluid therein becoming, of course, stronglyheated is forced continuously downward out of the tube A B, and impingesagainst the plate 0 more strong- 1y, thus producing an intensely-heatedcircular horizontal flame, having a diameter of about six inches, moreor less, the burner being of about the size shown in the drawings.

The whole burner is simple and inexpensive of construction, not liableto derangement,

and is more effective for heating and cooking by the combustion ofhydrocarbons, either crude or refined, than any other device known.

Having thus fully described my improved burner, what I claim as newtherein and of my invention, and desire to secure by Letters Patent, is

In a hydrocarbon burner for heating and cooking, the combinedarrangement of a bent heating-tube, A B, and a heating-chamber, C, soconstructed as to operate together substantially as described and setforth, for the purposes specified.
